8 Simple Questions You Won't Believe Science Can't Answer

#4. How to Beat Solitaire

Odds are pretty high that you're reading this article while you're at work. And once you're done wasting time with Cracked, odds are you'll continue to waste time with something else. And conveniently at your fingertips is one of the most played and addictive games of all time, one that you don't even need a partner for: solitaire.

More specifically, Klondike solitaire, which is as familiar to career procrastinators as Minesweeper. All of us at some point, usually around our 10th consecutive loss, have buckled down and tried to figure out the secret. After all, if Rain Man can break Vegas, surely you can beat a goddamn Windows game.

Wrong!

Maybe it has something to do with the fact that scientists get distracted when "studying" solitaire, or the fact that solitaire may have evolved from freaking black magic, but pretty much every damn thing about the game has remained a mystery since the 1800s. In fact, big-time mathematicians openly admit that it's one of the "embarrassments of applied mathematics" that almost nothing about the standard Klondike solitaire game is currently known.

For example, when the math geeks tried to find the odds of winning, they ran into a problem. They couldn't even get a fixed idea of how many winning hands are possible. The mathematicians came up with an approximate percentage of how many hands are winnable that was somewhere around 80 or 90 percent. But think about it -- when you play solitaire, do you win at least eight out of every 10 hands? Either you have the lamest X-Men superpower ever, or you're lying.

GettySorry, kid. No one in history has ever gotten laid for their ability at solitaire.

Now, there's some wild-ass guesses out there as to what the actual odds of winning Klondike are, but you'll never get an exact answer, even if many computer people agree that you don't have a good chance of winning at the game.

You might think that it's just because scientists are too busy breaking apart neutrons and quarks to bother trying to hack a card game. But consider that science has already cracked the secrets to the seemingly much more complicated game of Monopoly. But solitaire? It's simply beyond our powers of understanding. Then again, if we actually did know how to beat solitaire, we'd have to go back to work faster.

#3. How Many Species of Animal Exist

In the 21st century, the days of Marco Polo and Columbus are long behind us. Nobody is exploring new lands and finding exotic new creatures like the platypus for the rest of the world to call bullshit on. So surely, having stomped across every nook and cranny of this blue earth, we should by now have some kind of ballpark figure about how many species we have left to kill, right?

GettyGotta catch 'em all!

Actually, not even close. When you ask taxonomists (scientists specially tasked with finding and cataloging animals), they'll tell you they haven't even scratched the surface in their attempts to find all the creatures that live on the planet. However, despite working on this mission for almost 250 years, along with discoveringover 15,000 new living beings each year, taxonomists don't even have the faintest idea of how many species live on Earth.

One of the early estimates from 19th century taxonomists said that there were about 400,000 species on Earth, and seeing as how we've already discovered five times that many, it's only logical to conclude there was some faulty sciencing involved there. In fact, the most recent estimate, which claims that that there's less than 10 million species, is being heavily criticized by scientists. Hell, even the people who put out this estimate admitted publicly that they might be way off.

#2. The Length of the U.S. Coastline (Or Any Coastline, For That Matter)

Of all the subjects we learned in high school, the one with the least amount of mystery was probably geography. The continents, rivers and mountains aren't going anywhere. At least not very fast, they're not. Sure, the fine points can get more complicated. Maybe the tallest mountain isn't the one you think, and maybe the largest desert will surprise you, but even then, it's all just a matter of committing definitions to memory and spewing them back to your teacher. It's all freaking measurements! Surely the length of the United States coast isn't something "up for debate."

GettyWhat do you need besides a ruler?

Yet estimates vary wildly. The Central Intelligence Agency, for example, officially lists the length of the U.S. coast as around 12,380 miles. But another study came up with 29,093 miles. Then this study from the National Oceanic and Atmospheric Administration (a U.S. government agency) came up with 95,471.

What the hell?

You see, measuring coasts isn't simple and indisputable, like measuring a straight line on a piece of paper. It's complex and prone to wild exaggeration, like measuring your dong in the bathroom. The reason is that, depending on how much detail of a coast you want to measure, you'll always get a different final outcome from someone who chose to take into account a different amount of detail. If you want to just take the rough outline of a coast, you can get a measurement like the CIA has. But when you get into the fine details of every little inlet and estuary, suddenly the numbers get much bigger as you calculate in all of these twists and turns.

And the thing about all those numbers is that they can all be adopted as "official" measurements by government agencies, and nobody would bat an eye. In fact, the disparity between coastline measurements is accepted and is a pretty well-known problem in geography dubbed the "coastline paradox." This coastal conundrum comes from the fact that, no matter how much detail you choose to take into account in your measurement of a coastline, no matter how many of the zigs and zags you measure, there is always more detail to get. This paradoxically makes every single coastline of every single country infinitely long.

#1. How Gravity Works

Come on, it's gravity. Is there any concept in the universe quite so basic? You throw shit up, it comes down again. Despite his textbook reputation, Newton didn't discover gravity. It was discovered by the first fish ancestor who crawled onto land and found it had lost the ability to swim upward. What's to understand?

GettyOne aborted attempt at parkour and the subsequent ER visit can drum the basics into even the thickest skull.

Turns out there are four basic forces that hold the universe together, and out of these four, gravity is the only one that doesn't make any sense. Specifically, how it can be so incredibly weak and incredibly strong at the same time. Gravity holds the entire universe together, and no matter how far out you travel, it never completely disappears. And yet, it is the weakest force in existence. To illustrate, you know when you bring two magnets near each other and they snap together? That force is actually 10^36 times stronger than gravity. Yeah, the technical term for that is "a big-ass order of magnitude" stronger.

Getty"Using the scale devised by Dr. R. J. Fuckton, of course."

To add to the confusion, because all these other forces are controlled by their own particles, it stands to reason that gravity should have its own particles, too. But this hypothetical critter -- the graviton -- is basically the only one we haven't found yet, unlike the particles that mediate a lot of the other important forces in nature, which have been altogether more cooperative.

But the mother of all baffling gravity mysteries is that, once you get down to the level of atoms and molecules and even smaller stuff, gravity just plain stops working. In fact, gravity is one of the biggest reasons why quantum physicists and real-world physicists have nothing to say to each other. We know more about what's inside an atom than we do about why a ball comes back down when we throw it in the air. For all science knows, it's because of ghosts.
